The Line Magnetic 805iA uses single-ended triode 805 tubes and operate in pure Class A. It delivers 2x48W power. It has 3 unbalanced line inputs, 1 bypass input and 4, 8, 16Ω output groups. The rear-illuminated front panel meter is used to adjust the polarization of the tubes.

The use of high-quality components (Mundorf N-Cap capacitors, ALPS potentiometer) wired in the air for the most part is the guarantee of exemplary reliability. Its power and current capacity allows it to manage a very wide range of speakers. The use of the legendary triode 805 offers a listening to an unusual musicality.

The LM-845 Premium is the result of many years of research on the 845 triode Single ended design. Thanks to its exceptional design and manufacturing quality, it is fast fast becoming the absolute reference in the high end amplifiers world.

With a power output of 2x30W, it can be use with most of the existing reference speakers.

The LM-845 Premium is a combination of two units: One is the amplifier unit and the other is output unit.
The LM-845 Premium uses Shuguang 300B tubes in drivers, the 310A for amplifier and Shuguang 12AX7 in pre-amplification.

There are two user bias controls for 300B and 845 have been used for bias adjustment and two meters has been added to the front plate to allow you to monitor bias with ease. Negative feedback switch is on the front plate that you can choose betweeen two levels of NFB to enjoy the different sound outputs.

The LM-845 Premium uses 8 transformers (power supply, filtering, coupling and output)!

Forty-two watts per channel, Class AB Integrated Stereo Amplifier with KT88 (JJ Electronic) output power tubes, 6CL8A (Mullard) and 12BH7 (Electro Harmonix) input tubes.

LM-88IA Amplifier can operate in two different ways Auto-biased or Fixed bias. You can select the one you prefer. Power output for Auto-bias mode is 45 watts while for fixed bias it is 30 watts per channel.

Specially designed Toroid transformers made of Z11 Core fort power supply and two Japanese Audio grade EI types of output transformers with wide bandwidth are applied. All transformers and chokes are encapsulated and installed separately on the amplifier to avoid and lower the disturbance between each other.
